Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early failure symptoms include audible humming or grinding sounds and excessive heat generated by the component. Continued operation can lead to severe wear on mating surfaces and potential seizure of the associated assembly. This risks significant damage to the powertrain or drivetrain components.

Installation Tip

Ensure the shaft and housing surfaces are meticulously cleaned and free from any imperfections before installing the bearing. Never use a hammer to drive the bearing onto the shaft; use appropriate press tools.

Service Note

Inspect the surrounding seals, shaft, and housing for any signs of wear or contamination when replacing this bearing.
